I find it approachable for someone that doesn't know FP. It doesn't require shifting all of your knowledge and habits at once. It might not teach you everything there is to know about FP but I think the question originally was roighly "is it hard to learn if you don't know FP?"

And I'd say for that type of case it may be more approachable for not being qiite so pure.

Approachable it certainly is, I'm not disputing that at all. The less functionally aligned a language is the more approachable it is to developers with little to no exposure to FP.

Personally, learning Elixir didn't really help me understand many fundamental FP concepts such as function composition & higher order functions, algebraic data types, referential transparency, functional purity, currying etc. It was only after spending time learning Elm and Haskell that many of these things dawned to me.

So I'd say if your aim is to really learn about the functional programming as a paradigm, there are better alternatives out there.
